Cognitive mobile terminal wireless network system and network self-organizing method

Abstract

The invention relates to a set of emergency communication system which is composed of a general packet radio service (GPRS) cellphone terminal, a base station system and a mobile switching center (MSC). A global system for mobile communications (GSM) emergency system can be formed in a small scope, when a base station is destroyed, an emergency networking function is started in a manual starting mode, network self-organizing is conducted, and a local area wireless network system with a GPRS cellphone terminal being as a node is formed. A network forms two nodes in a self-organizing mode through a competitive mechanism, the two nodes are a cluster head node and an internal network node. The cluster head has the function of a base transceiver station (BTS) and replaces the BTS temporarily. The cluster node and the BSC are in wireless connection, the internal network has the function of the cellphone terminal, through the cluster node, and transmissions of internal network and voice communications are achieved. The emergency communication system is a wireless communication system in emergency, the difficult problems of local contact and contact with the outside when the base station is in breakdown or destroyed in emergencies such as a typhoon, an earthquake and a storm tide are solved.

Description

technical field [0001] The present invention is a set of system, the system is composed of ordinary mobile terminals, when an emergency occurs, the emergency networking function is activated manually, and the network is automatically organized to form a network that can communicate in the local area and communicate with other networks wireless network system. Background technique [0002] At present, most of the ordinary mobile terminals that can access the GSM cellular network, local area network or Internet network use the general packet radio service GPRS mode for communication. Point-to-point TCP connection for data communication, so in an emergency situation, when communication with the external network is impossible, ordinary mobile terminals can be used as a wireless local area network system composed of nodes to transmit information between networks, and at the same time conduct network searches. When connecting to other network devices, it can be accessed to get in...

AI Technical Summary

Problems solved by technology

For MS to realize normal communication, BTS, BSC, and MSC must work normally. When BTS is damaged or destroyed and cannot work normally, the network communication in a certain area will be paralyzed

Therefore, it is necessary to build a GSM emergency communication system that can be used within a certain range in order to solve the problem of GSM communication interruption or paralysis caused by natural disasters
